Strange. With the same error messages (except: "Enclosure added: encl=0" because the controller dont have that feature) you post, a 9550SXU-4LP of mine died some days before, crashing the whole system even if no system files where on it. It performed well for 2 years and 11 months under FreeBSD 7.x, so it is still under warranty and LSI will replace it, .
